Hi @sanjana12 ,
In transactional message, rtEvent and ctx parameters are declared under domEvent.
In rtEvent, type being the template event type and email being the recipient email address is declared.
In ctx, all the attribute used on the template must be defined.
For example, if the event type of the template is 'email_verification' and email address is 'test@test.com' and content is 'Hi firstName lastName',
then SOAP call will be,
<urn:domEvent>
<rtEvent type="email_verification" email="test@test.com" >
<ctx>
<firstName>Partha</firstName>
<lastName>Sarathy</lastName>
</ctx>
</rtEvent>
</urn:domEvent>
